In combination with actual project cases, the paper introduced the post-grouting technology of cast-in-situ piles, and analyzed the application of post-grouting technology of cast-in-situ piles in city overpass bridges. Meanwhile, through analysis on experiment results, the increasing coefficients of both the pile side friction and the pile tip resistance, which arose from the composite post-grouting technology, were obtained in this paper. And this proves that the composite post-grouting technology can be conducive to increasing the pile foundation bearing capacity and decreasing the project investment considerably.
